Abstract: An animation file player can display animation files with an embedded system graphics application programming interface (graphics API). In an example implementation, an animation file comprises a Flash® animation file such as, a Shockwave Flash® animation file, and the embedded system graphics API comprises an OpenGL®|ES graphics API. The present invention is not intended to be so limited, and other types of animation files and embedded system graphics APIs can be used.

Abstract: A method, system, and computer program product are provided for accelerated shading of an object surface by bump mapping in tangent space or object space. A tangent space transform module builds a tangent space transform matrix M(p) having elements comprised of normal, tangent, and binormal vector components determined at a surface point on the object surface. The tangent space transform module further transforms shading vectors, such as, lighting and viewing vectors, into a tangent space defined by the tangent space transform matrix and outputs corresponding tangent space shading vectors. A bump mapping module performs vector operations between one or more tangent space shading vectors and a perturbed normal N' in tangent space. A texture memory stores a surface dependent or a surface independent tangent space perturbed normal texture map. The lighting module computes a shading value for the surface point based on the vector operations.
